I've been testing this for the month of January. It is a very concentrated serum that is loaded with vitamin C, which is a powerful anti-aging agent. When you put a few drops of this on your skin every morning, it lasts for up to 72 hours though you wouldn't notice it is there. This is the kind of product that you need to use for at least a month consistently every day to get the full benefits. It has a bit of a scent when you put it on (if I say it reminds me of molasses does that make sense?), but it instantly fades to nothing. The scent is not unpleasant.

SkinCeuticals products are expensive but they are very effective. I did notice the first few times I used the product that my eyes were a bit itchy. I don't know if it was directly related to the product because I didn't put it near my eyes, but after a few days that stopped so I'll never know. My skin looks healthier and more radiant when I use this even though I've been sick a fair bit this month.

My regimen at the moment is almost entirely SkinCeuticals serums. I did not noticed a radical difference but I stopped using the S.C products for a few days here and there to test other products and my skin was not pleased. I developed dry flakes on my face and some blocked pores. This product will never block your pores because it's not a cream.

I got my product from the PR company, which was a huge blessing since it retails for $86 for 30ml. You only need a few drops of the product so it lasts a while. I've used roughly 1/3 of the bottle in 30 days.
